The tulip.xio module contains IO functions that extend Lua's standard io module.

#API

Assuming local xio = require 'tulip.xio'.

#s = xio.b64decode(s)

Decodes s which is a base64-encoded string using URL-safe characters. Returns nil if it was not properly encoded.

#s = xio.b64encode(s)

Encodes s into a base64 string, using URL-safe characters.

#tok = xio.random(len)

Generates a random token of the specified length.

#n = xio.randomint([n])

Generates a uniform random integer between [0, n-1]. If n is omitted, the interval is [0,2^64−1].
